manufactured products are made from seeds ? See Applied 

 Work on Seeds. 



6. Seed Table 



Make a list of all the seeds used in your home, in what 

 form used, and for what purpose. 



7. Vegetable and Flower Seeds 



Write a statement of the seeds used in gardens (the home, 

 market, and florists') and on the farm. 



What do you find out about the importance of seeds for 

 these purposes ? Examine garden catalogues. Find out, 

 if possible, where garden and flower seeds are grown in 

 great quantities for sale. How do you account for the very 

 great number of kinds of different seeds, for example, of 

 beans, there being originally only about four distinct sorts 

 or species and now the varieties number about 400 ? 



8. Applied Work ox Seeds , 



Practical applications of the facts learned by the study 

 of different seeds, based upon the experience of the pupil. 



1. The Starch Industries. Soak a number of kernels of 

 white corn, remove the embryos ; dry thoroughly, crush, and 

 remove the seed coats. Pulverize the remaining part most 

 thoroughly in a mortar. When very fine, stir thoroughly in 

 cold water and set away in a clean quiet place to settle. 

 When this is accomplished, pour off the water and any 

 loose material. The solidly deposited residue will be found 

 by the iodine test to be almost pure starch. This illustrates 

 in a crude way the immense starch manufacturing of the 

 United States from corn. Many chemical and mechanical 

 means are added to secure a pure product. 



Compare your product {hp) with cornstarch and laundry 

 starch. Add boilin.G: water and observe the result. Take
